bLLLEIfCE DOOLEY, OF LOCK ISLAND, ILLINOIS.

To all whom it may concern:

Be it known that I, CLARENCE H. Doom-1r, a citizen of the United States,residing at Rock Island, in the county of- Rock Island and State ofIllinois, have invented certain .new and useful Improvements inPlanters, of which the following is a specification, reference being hadtherein to the accompanying drawing. r

This invention relates to improvements in planters and more particularlyin those parts of planters whic furrowsto receive the seed.

The invention is especially applicable to corn planters having a seedboot, through which the seeds pass on their way from the hopper to theground, and a furrow opening runner which is secured to the lower end ofthe seed boot.

,The. object of the present invention 1s to provide an improved bootconstruction and improved means for fastening the runner to the'seedboot.

Referring to the accompanying drawings-Figure 1 is a side elevation of aseed boot and runner embodying my invention, some of the parts beingbroken away {1 nd 1g. 2 is a'vertical transverse section on the line '22of Fig. 3. Fig. 3 is a side elevation of the seed =boot. Fig. 4 is aplan view of the runner; and Fig. 5- is a view showing one of the runnerholding blocks.

In the drawings 2, 2, represent the main bars of the front frame of aplanter. To these bars there is secured the seed boot 5 through whichseeds are conducted from 'a seed hopper (not shown) to the ground.

The passage of the seeds from the lower end of the duct to the soil iscontrolled by a movablevalve 10.

6 is a runner adapted to open a furrow to receive the seeds, the rearend of the runner being rigidly secured to the lower end of the seedboot, and its front end being supported by a brace bar 7 to which it issecured by bolt 8.

The runner which I have designated, as an entirety, by the numeral 6comprises a main body part and a rear forked part, the two branches ofwhich are designated 6, 6. In making the runner, oneof the branch plates6 is preferably integral with the main part while the other branch part6 is welded thereto. I-leretofore, in making this part of a planter, ithas been customary to secure .are used for openingrmrnn.

these runner blades to the lower end of the Specification of LettersPatent. Patented July 15, 1913. Application fled larch 24, 1910. SerialNo. 551,286.

cast shank, or boot, by means of one or more rivets arrangedhorizontally and passing through the blades and through the lower partof the shank. To receive these rivets, countersunk apertures must beformed in the blades, and the heads of the rivets must be up-set in suchway that they will fill, but not project beyond, the countersunkapertures. The earth contacting surfaces of the runner blades must beperfectly smooth. and unobstructed, so that they will form clean shallowfurrows. These surfaces must be self scouring, and devoid ofobstruct-ions, such as would catch straws, stalks, or other trash. Hencethe necessity of countersinking the rivet apertures, and upsetting therivet heads, so that smooth surfaces shall be produced. But seriousdisadvantages are incident to this manner of making and fastening therunners. In some soils they rapidly Wear to such an extent as to becomeinoperative or seriously impaired. Again they require frequentsharpening. And in case of fracture another must be substituted. \Vhen,because of any of these reasons, it becomes necessary to remove arunner, and subsequently replace it, or substitute another for it, aserious problem or difiiculty is presented to the farmer. He has to loadmore or less of the planter upon a vehicle,-

extension 10. The thickness of the extension 10 is less than that of thefoot 9 so that downwardly exposed shoulders 11, 11 are formed. Theextension 10 has inclined surfaces 10 10 between which is formed arecess 12.

13 is a hole formed to receive a connecting bolt.

The depending extension 10 serves not.

only as an abutment for the runner securing parts to be described, butalso as a seat or ledgefor the seed valve 10.' As will be noted from aninspection of the drawings,

this valve is located immediately above the upper inclined'surface ofthe extension or valve seat and at the lower end of the "duct throughthe seed boot 5. i 1

' rivets and 16. The block 14 is formed with inclined faces 14 and 14adapted to fit the faces 10 and 10", respectively, of the seed bootextension 10. And the block 14 is formed with a lug 17 which is adaptedto enter the recess 12 of the said extension 10. i y

18 is a hole to receive the fastening bolt 19, this hole 18, as Well asthe whole 13, being made somewhat larger than the bolt 19 so that exactalinement of the two holes is not essential. It will be seen that whenthe parts are assembled and the bolt 19 drawn up by tightening its nut20 the face 14 of the block slides upon the inclined face 10 of theextension 10, bringing the lug 17 of the block into tightengage'mentwith the recess 12, thus rigidly locking the runner to y wardprojection at the bottom of the shank,

the boot. When the parts are thus locked together, the upper edges ofthe runnerblades (3,6 lie under'the shoulders 11 of the boot, thusforming a smooth exterior at p the junction of the parts.

When the bolt is arranged in the way illustrated, and described, thereare no pro- 'jections extending outward fromthe earth contactingsurfaces of therunner blades, so that these surfaces remain permanentlyself scouring and have no tendency to catch trash or foreign materialsto interfere with the forming of a smooth, shallow furrow.

When the farmer desires to remove the runner for any purpose it ismerely re quired that he shall loosen the bolt 19., and also that at.,8.For all ordinary purposes,

he is equipped on -the farm for effecting the operations that aredesired after the removal of a runner, such as re-shaping when bent,sharpening it, or the substitutin of a new one. In the unusual eventthat %lackmemos he has to. carry to the shop is the runner itself,

Both in, the blacksmith shop and in the factory where the machines areori inally made, the riveting of the runner to t e cast shank or bootresults in the breakage of a large percentage of the shanks. In the shopcost alone, there is a great saving by having the fastening devices forthe rear of the runner detachable in the way I have described.

What I claim is.-

1. In a planter, a tubular shank having a downward projection providedat its rear side with a valve seat and at its forward side with a runnerretaining surface, a valve movably associated with the valve seat, a

bifurcated runnerembracing thesaid prodownward exposed shoulders beingformed between the projection and the shank proper, the said projectionhaving a valve seat at its rear side, and an inclined irregular surfaceat its forward side, a valve movably associated with the said seat, abifurcated runner embracing the-said projection and valve and having itsforks in engagement with the said shoulders, a block secured between thesaid forks having an irregular surface corr sponding to and contactingwith the irregular surface of the projection, and means for detachablysecuring the runner. 1n position with the two irregular surfaces inengage- *ment, substantially as set forth.

In testimony whereof I aflix my signature, in presence of two wltnesses.
